Scientists have come a step closer to the vision of a broad application of flexible, printable electronics. The team has succeeded in developing powerful vertical organic transistors with two independent control electrodes.

High-definition roll-up televisions or foldable smartphones may soon no longer be unaffordable luxury goods that can be admired at international electronics trade fairs...

Until now, the history of superconducting materials has been a tale of two types: s-wave and d-wave. Now, Cornell researchers — led by Brad Ramshaw, the Dick & Dale Reis Johnson Assistant Professor in the College of Arts and Sciences — have discovered a possible third type: g-wave.

Their paper, “Thermodynamic Evidence for a Two-Component Superconducting Order Parameter in Sr2RuO4,” published Sept. 21 in Nature Physics...

Engineers have invented a soft wearable device which simulates the sense of touch and has wide potential for medical, industrial and entertainment applications. What if you could touch a loved one during a video call — particularly in today’s social distancing era of COVID-19 — or pick up and handle a virtual tool in a video game?

Pending user tests and funding to commercialise the new technology, these ideas could become reality in a couple of years after UNSW Sydney engineers developed a new haptic device which recreates the sense of touch.

Haptic technology mimics the experience of touch by stimulating localised areas of the skin in way...

Material could be used in smart textiles, medical devices and more. Researchers have developed a biocompatible material that can be 3D-printed into any shape and pre-programmed with reversible shape memory. The material is made using keratin, a fibrous protein found in hair, nails and shells, extracted from leftover Agora wool used in textile manufacturing. It could be used in anything from self-fitting bras to actuating textiles for medical therapeutics and could help reduce waste in the fashion industry.

As anyone who has ever straightened their hair knows, water is the enemy. Hair painstakingly straightened by heat will bounce back into curls the minute it touches water. Why? Because hair has shape memory...
